I would never in a million years, as a developer, give my personal phone number to a client. That's probably why. I get the same issue where I work. The client states that "everything is broken," but it often turns out that their own servers are down (or sometimes our API guys made a breaking change and I wasn't informed, but that's not common anymore). I find this stuff out when I get to work in the morning, because they certainly aren't calling me directly.
